摘　　要：通过测定水牛乳的滴定酸度、乳成分及64%、66%、68%、70%(V/V)酒精试验,分析酸度及乳成分对水牛乳酒精阳性发生率的影响,探讨酒精试验用于水牛生乳计价及拒收依据的可行性。结果表明,64%的酒精更适用于水牛乳,但仅能作为初步或辅助的品质评价手段;通过分析乳成分对不同酒精浓度下低酸度酒精阳性乳发生率的影响,表明蛋白质、乳糖加灰分含量越高,低酸度酒精阳性乳发生率越高,但脂肪含量对低酸度酒精阳性乳的发生无显著影响。The titratable acidity,milk composition and alcohol test at the alcohol concentration of 64%,66%,68%,70%(V/V)were detected for studying the influence factor of alcohol positive milk(APM)occurring rate,and discussed the applicability of alcohol test on buffalo milk quality evaluation.The results showed that alcohol concentration of 64% was more suitable for buffalo milk alcohol test as the preliminary and accessory method,but only could be used as an initial or auxiliary means of quality evaluation.Through analysis different milk composition on the influence of the alcohol concentration and low incidence of acidity alcohol positive milk,the APM occurring rate increased with the rising of protein and lactose plus ashes content,and there were no significant changes for the fat content.
